Abstract
In order to determine layout location of variable message signs (VMS) scientifically and reasonably and give full play to its transportation guidance effect, the optimal selection method of expressways VMS layout location is studied based on general rules and requirements of expressways network VMS layout. Construct the multi-objective optimization model of VMS information utilization maximum, VMS effectiveness and VMS total cost minimum based on fuzzy constraint conditions, and the Hang-Jin-Qu expressway VMS layout is analyzed. The results show that the proposed multi-objective optimization model is more in line with the actual need of VMS layout and easy to operate, and has important practical value.
